1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.
GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.

Give two similarities and two differences between gymnosperms and angiosperms.
kakasveta [241]

<span>Similarities</span> between Gymnospermes and Angiospermes:


<span>·         </span>Having seed-Gymnospermes and Angiospermes are types of plants bear seeds. They belong to a single class known as Spermatophyta. Spermatophyta or seed plants are those <span>plants that produce seeds.</span>

<span>·         </span>Diferentiation- The sporophyte (diploid multicellular stage in the life cycle of a plant) of both,<span> Gymnospermes and Angiospermes,</span> is differentiated into root, stem, and leaves.


Differences between Gymnospermes and Angiospermes:

 

<span>·         </span>Seed-Although both have seeds, differences between them are huge. Gymnospermes have bare, non-encased seeds. The term "gymnosperm"  in Greek means "naked seeds". On the other hand, seeds of Angiospermes are enclosed within an ovary, usually in a fruit.

<span>·         </span>Pollination- In Gymnospermes, the pollination is by wind, unlike most Angiosperms, who use insects, mammals or birds.  Gymnosperm flowers are often difficult to spot because they are not out to attract flying pollinators.
